Re: Solar power Basics
A little "abstract reasoning" here:
Based on the 175 Watt panel. 1 electrical HP = 746 Watts = 4.25 panels @ 33 lbs. each = 140.25 lbs. per HP
And that's at 100% efficiency and just the panels' weight. An economy car has a power-to-weight ratio of around 20 lbs. per HP. Each panel is approximately 6 sq. ft. * 4.25 = 25.5 sq. ft. "Footprint" of a small car = 5' * 15' = 75 sq ft. The panels for 1 HP would take up 1/3 the area of the car.
Want to see how bad it gets? Add the over-all efficiency of a solar conversion on a flat plane of about 50% - that is, the power is cut in half. Add the weight of the mounting, wiring, and other electrical necessities as well as the weight of the vehicle itself.
This is why you don't see solar powered cars around.
Four 175 Watt panels, OB MX60, 232 Amp hrs, OB 3524, Honda eu2000.
Ohm's Law: Amps = Volts / Ohms
Power Formula: Watts = Volts * Amps
